Warren Buffett revealed he personally initiated Berkshire Hathaways investment in Alphabet, lifting the stock nearly 4% and adding over $15 billion to the combined wealth of Google co-founders Larry Page and Sergey Brin. Berkshire now holds Alphabet among its top five investments, while strong AI-driven growth, cloud expansion, and increased spending plans continue to support investor confidence.

Berkshire Hathaway disclosed its first investment in the Google parent last year.

Warren Buffett said he was the driving force behind the conglomerate's recent big investment in Alphabet.
